speci'ca'tion of Letters Patent. Application filed March 23, 1908'.

Patented March 23, 1909. seria1No.422,61o.

To all whom 'it may concern:

Be it knownthat I, Josnlrr E. SYMoNs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful which the following 1s a specification.

My invention relates to axles and has for its object to provide certain new and useful mplilovements hereinafter more fully set ort v It is illustrated in one form in the accompanying drawings, wherein-v Figure l is a side elevation of a finished axle with parts broken away; Fig. 2, a plan of the sheet metal blank; Fig. 3, a longitudinal section through the end of the completed axle Fig. 4, a cross section on line 4-4 of Fig. 3,' Fig. 5, a cross section on line 5-5 of Fig. 3, and Fig. 6, a similar cross section showing a slight modification.

Like parts are indicated by the same char,-4

acters in all the figures. n

A is a blank having the tapered ends A1 A1 and the central enlargement A2. Y p B is a ller or former preferably of wood or similar material and preferably integral, but in any event, provided with taperedends B1 B1. There should be one such tapered end at each end of the complete axle.

C is the axle skein shaped preferably as shown, of any desired material and provided with an inner enlarged extension C1 to be received over that portion B2 of the core which connects the central portion with the end. The part A2 is bent over as indicated in Figs. 5 and 6, and turned down on one side, and the overlapping portions of the metal sheet are then secured by the screws D, D or the bolts D1.

E is a screw whereby the skein is secured to the end of the core.

F is a nut screwed onto the outer end of the skein so as to hold the wheel on. 1

The use and operation of my invention are as follows: The core is a former about which the sheet metal blank is wrapped, the latter being bent around the core as upon a former. The overlapping edges of the middle portion of the blank are spiked or held in place.

he wrapped portion of the sheet metal Which surrounds the tapering core ends is preferably arranged so that a slight interval is left between its contiguous edges when so wrapped. The end of the axle thus presents a tapering core with an inclosing sheath, the

' tapered ends and whole'more or less yielding to receive and accommodate itself to the skein. In this case the core is entirely inclosed or wrapped. The parts are shaped so that the wrapping or sheath presents extended substantially vertical surfaces to give greater strength. Moreover, the overlappingof the edges of the sheath results in further strengthening the axle in the direction in which it needs strength. Experience has shown me that such axles are liable to break at the point where the tapered end makes connection with the enlarged or upwardly rising axle body, and I have, therefore, extended the skeinvand have thickened the core at such point, as indicated in Fig. 3.

- of course, assume various forms, but a portion ofV my invention is the arrangement of this sheet so that it shall take the shape of two flat plates on opposite sides of the core or former, or space which such former would occupy if it were continuous and complete; The two plates, therefore, have great strength and this strength is as suggested, increased where two sections of the plate are overlapped. This feature of the invention, could, of course, be obtained without having all the other features referred to.

Where I use the term core or wooden core I mean to imply so much of the core as may be necessary, particularly at the taperedends and a core which is substantially wooden or to a certain extent yielding .and elastic.

I claim:

1. An axle comprising a wooden core with homogeneous tapered ends and a thin metal sheath entirely inclosing the core, its ends permanently wrapped around and set in position about the body and the tapered ends of the core to form relatively yielding` metal covered tapered axle ends to receive the skeins. i

An axle comprising a wooden core with a thin metal sheath en tlrely inclosing the core, its ends permanently wrapped around and set in position about the body and the tapered ends of the core to form relatively yielding metal covered tapered axle ends to receive the skeins, i its ends permanently Wra ped around and said eore provided With substantiallyrverti# "set in position about the ody cal sides intermediate the tapered ends and peredends oi? the eore to forni relatively yieldsaid sheath lying parallel to suoli sides. ing` tapered axle ends to receive the skeins.
